Answer:
ACT score
It has a higher standardized score than his SAT
Step-by-step explanation:
Obtain the standardized score for both SAT and ACT
SAT:
Mean = 515
Standard deviation = 115
Score (x) = 610
ACT:
Mean = 21
Standard deviation = 5.1
Score (x) = 27
ZSCORE for SAT:
Zscore = (x - mean) / standard deviation
Zscore = (610 - 515) / 115
Zscore = 0.826
ZSCORE for ACT:
Zscore = (x - mean) / standard deviation
Zscore = (27 - 21) / 5.1
Zscore = 1.176
He should use his ACT score has it has a higher standard score than his SAT score. Hence, his ACT score weighs higher Than his SAT score
